QAV-M 114 // Babyhawk rebuild

Despite it being pink, which is usually an instant win in my book, I was always slightly disappointed by my Babyhawk, largely due to the complete lack of camera protection (I broke the camera on literally the second outing). So I figured I'd see if 3D printed PET-G was a plausible option for something this small & with such minimal weight.

I went with a R9 Mini simply because it's both smaller & cheaper than any of the 2.4GHz receivers from FrSky, even if the long dipole antenna is a bit awkward on such a smol frame.

Dry weight is 77g, so notably up compared to the ~64g of the Babyhawk, but ain't it just the cutest?

hey,
Nice colors :)
I'm building a similar, albeit smaller, micro and have annissue mounting the Foxeer arrow

Did you 'just' zip tie the camera? No seat nothing? And how can you angle it?

Thank you!

It was just zip ties to the top plate, which gave it a bit of upward tilt. It's not a great solution, it needs longer standoffs to allow more than a very acute angle because the camera/VTX is just too big otherwise.

video?

Neat! I wonder if you could just zip tie the antennas along the arms for better protection. It's not carbon and should not affect the antenna performance.

I tried & it didn't make much of a difference, still sticks out ~1" at either end.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
